It has a thick, rich texture and contains stabilized vitamin C. It gives the impression of a rich serum?! It has a slightly artificial scent, but if it's effective, I don't mind. I used the face wash from the same series, then the lotion, and then this serum. It absorbs very well. It spreads well and blends well into the skin. However, when I use this, I get small whiteheads. Maybe it's too rich for me. The next morning, my skin's surface was smooth, and I could feel the tightening effect on my pores. It also feels moisturized. Because it's expensive, I've reduced the price by 1 star to 4.
I received a sample. It's a rich oil that smells similar to an overseas supplement oil. It's sticky, but the next day my skin felt firmer and my pores tightened overnight. It may be the most effective serum I've ever used. I think it's great for the dry autumn and winter months. It might be a bit tough to use when the humidity starts to rise, as it can get sticky.
It goes very well with the enzyme cleansing powder. It's thick and viscous, and I'm happy that the medicinal scent of the active ingredients seems to work. It's reliable and replenishes with oil. The stable vitamin C derivative conditions the skin. The beneficial ingredients promote collagen production, give firmness, and reduce fine wrinkles.
I used a sample. It has a thick, yellowish texture and is easy to apply. It doesn't have a strong, but slightly medicinal smell, so some people may not like it.
The smell is a bit bothersome, but I'm hoping it will moisturize.
